Hi all! Recently bought a 1979 17000 which appears to have a non tritium dial and a non open 6&9 date and mint hands. So I assume it may have had an overhaul. However it's losing 2 sec a day and have noticed it loses a lot more time and randomly stops ticking when I have my air conditioner running and my room cools. Seems to struggle when the watch is at 20-22c.
Anyone ever had such issues?
Guess it's off for a service. Also battery was replaced hoping it would resolve the issue.
Thanks!
